Shiozawa tsumugi is a silk textile produced in the former town of Shiozawa (now a part of the city of Minamiuonuma), Niigata prefecture. This craft is notable for using kasuri patterns. These patterns include the finely detailed T-shaped pattern or ka gasuri, a cross pattern or juji gasuri, and a tortoise shell pattern also called kikkou gasuri. The fabric is a single base color in cool tones, mostly navy blue, black or white which combined with a black kasuri pattern, possesses an elegant appearance.
